Hello Sorry for disturbing again. It looks like I must pass lot of compilation issues to force pam_smbpass working. And I don't believe, that nobody faced same problems as I do, because I am using quite trivial configuration without success, so maybes somebody can share experience with pam_smbpass under Solaris or help me identify what's wrong with it ? So finally I wrote my own pam authentication module to check how pam_smbpass really works. I see no problems no with module load as in my previous letter(well, only with this my program, not with telnetd or ftpd). But now I found another problem. In syslog file I see : Oct 24 17:26:37 local PAM_smbpass[13820]: [ID 743889 auth.debug] username [a0796999] obtained Oct 24 17:26:37 local PAM_smbpass[13820]: [ID 772098 auth.alert] Cannot access samba password database And I have no idea why.

No surprise, that it returns error about problem to open this file. Strings in pam module show correct filename for smbpasswd : # strings /usr/lib/security/pam_smbpass.so | grep "private/smbpasswd" /opt/local/samba/private/smbpasswd File smbpasswd exists on system. smbpasswd (compiled together with pam_smbpass) command works without problems : # ./smbpasswd -a martynas New SMB password: Retype new SMB password: # ls -al /opt/local/samba/private/smbpasswd -rw------- 1 root other 108 Oct 24 17:34 /opt/local/samba/private/smbpasswd What can be wrong ? Thank you in advance for your help. With best regards Martynas
